Alcoa started off earnings season on a rough note. The
aluminum producer missed on both revenue — posting only $5.21
billion against analyst estimates of $5.33 billion and earnings
per share — coming in at $0.32 per share against projections of
$0.34 per share. Alcoa's announcement also marks the start
of earnings season.

Illumina crashed. The biotech firm said that it would miss
its revenue guidance and analysts' expectations. After the
disappointing news, shares of the company tanked by 25% in
trading on Tuesday.

Samsung will no longer produce the Galaxy Note 7. The
phone-maker said it would stop production of its large
smartphone after the company was unable to resolve an issue
that caused the Note 7 to explode. The company had tried to
replace the part causing the problems, but they persisted and
led to the production halt.
